Description
The Eagle Nebula (M 16), located 1750 parsecs from the Sun, is the focus of this catalog. It contains X-ray properties for 1754 point sources, including 1183 candidate cluster members, derived from three Chandra/ACIS-I observations totaling approximately 238 ks. The data was produced by researchers analyzing the correlation between X-ray emission and stellar evolutionary stages in young clusters.
Use Cases
Compare X-ray luminosity functions between young clusters based on the analysis of M 16 and the Orion Nebula Cluster.
Investigate the correlation between X-ray activity and the presence of circumstellar disks based on the classification of 219 disk-bearing and 964 disk-less stars.
Analyze the spectral properties of OB stars to understand mechanisms for hard X-ray production.
Model X-ray spectra using thermal plasma or power-law fits based on source count thresholds described in the methodology.
Strengths
Contains data for 1754 distinct X-ray point sources.
Includes source classification for 1183 candidate cluster members based on optical and infrared properties.
Derived from three dedicated Chandra/ACIS-I observations with a total exposure time of approximately 238 ks.
